People not seeing facebook posts?

I've only got 35 people that have liked my page but everytime i post something it says how many people saw the post and it's only about 9 or 10 if that!! Why is that? How come everyone that has liked the page doesn't see it? xx

Hey Becca same thing happens to me, I've started to notice that not so many people can see my posts and my mum & sister did say the other day they haven't seen things I've posted recently come up in there timeline... Strange! Wonder if this has happened to anyone else ? Xx
